A cheetah is crouched 20 m to the east of a vehicle . Attime t = 0 the cheetah begins to run due east toward an antelope thatis 50 m to the east of the vehicle. During the first 2.0 s of the chase,the cheetah’s x-coordinate varies with time according to the equationx = 20 m + (5.0 m>s2)t2. Find its instantaneous velocity at t1 = 1.0 s by taking t = 0.1 s, then 0.01 s, then 0.001 s.
